WOW... I didn't think I would have to say this a day into voting.
Don't try and stuff the ballot box!
Congrats on knowing how to delete your cookies, but you can't delete your IP address. I can, and WILL, be deleting duplicate votes!
I am also able to see the time, so if say... 9 identical votes come in within moments of each other I'm going to consider it suspect, and I can cross reference the IP on the ballots to your AC account.
If you get caught stuffing the ballot box your AbsoluteChaos account will be locked. It's unacceptable, and I doubt the author you're trying to cheat for would appreciate winning like that.
Last and only warning. Thanks.
